Social Aggressiveness Scale in Adolescents: Validity, Reliability and Determining Factors

Introduction: Aggressiveness is a manifestation of violence that is most frequently evident in adolescence. An instrument is required that allows identifying behavioral problems in a premeditated and impulsive way, to establish an adequate coexistence. Objective: Determine the validity, reliability and determining factors of the social aggressiveness scale using an adolescent-oriented approach. Methods: Instrumental study carried out on 2184 students (49.04 % women), aged from 14 to 17 years (M = 15.39; SD = 0.98), distributed in two parts: validity and reliability (1100) and determining factors (1084). The measurement instrument was the Premeditated and Impulsive Aggression Questionnaire in Adolescents. Results: The questionnaire had a unifactor model with a McDonald’s omega coefficient of 0.85; an average trend was obtained in relation to the levels of aggressiveness, and statistically significant differences were found in relation to sex and the activities carried out in their free time, with a higher average range for men, and in those who spend more time on social networks. Conclusions: The social aggressiveness scale represents a useful instrument that should be considered in the educational field to identify behavioral problems.
